Product Summary

A thermostatic valve is a device that works behind the scenes to help achieve a desired temperature. It can be used for a range of purposes, such as maintaining a consistent temperature in a room or controlling the temperature output of water from a faucet or showerhead. There are several different types of thermostatic valves including mixing valves, shower valves, and radiator valves.
A thermostatic mixing valve is an apparatus that combines hot and cold water in order to produce a consistent temperature output. Mixing valves are often used to help regulate the delivery temperature of stored water, ensuring a safer and more comfortable water supply. Consider, for example, that most large-scale water supplies are stored at a temperature of 140°F (60°C) or greater in order to ensure that harmful bacteria is eliminated. A mixing valve helps prevent scalding or freezing water from spewing out when this stored water is released. Mixing valves are also often used to regulate temperatures in showers, sinks, and bathtubs.
A thermostatic shower valve is a type of mixing valve which can be essential when it comes to bathroom plumbing. For example, if a person is using the shower and a toilet is flushed or another faucet is turned on, the water temperature could change dramatically. As a result, the person in the shower could be scalded by hot water or shocked by cold water. The use of a shower valve helps eliminate these kinds of drastic changes in temperature.
Thermostatic radiator valves are typically used in hot water or steam radiator heating systems to help maintain a steady temperature in a room. They can experience variations in temperature depending on whether other heat sources, such as light streaming in from a window, are present in the room. As a result, they are usually used in buildings that do not require an exact temperature to be maintained.
